T-PIPE Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed April 3,1906. Serial No. 309,696.

'o all whom it may concern:

ABe it known that I, WILLIAM H. BELLMAINE, a citizen of the UnitedStates, and aY resident of Pocatello,

in the county of Bannock and State of Idaho, have invented a new andImproved T-Pipe, of which the following is a full, clear, and exactdescription.

The invention relates to a tee pipe or connection between the dry steampipe and the delivery steam pipes of boilers.

The underlying object of my invention is to provide a connection whichshall be readily accessible and less subject to temperature extremesthan heretofore, thus insuring an eflicient connection withoutinterfering with the usual repair and adjusting operations on theboiler.

The invention resides in certain special features of construction andarrangement which will be fully set forth hereinafter and particularlypointed out in the claims.

Figure 1 is a sectional view on the line 1-1 of Fig. 2 takenlongitudinally of the boiler; and Eig. 2 is a section on the line 2 2 ofEig. 1 taken transversely of the boiler.

10 indicates Vthe water compartment of the boiler, 11 the flues, 12 theflue sheet, 14 the smoke box with the opening 15 for the draft pipetodischarge the smoke, and 1G the dry steam pipe.

The tube or flue sheet 12 is formed with an opening 17 and fastened tothe front of the flue sheet 12 is a casing 18 having an opening 19therein registering with the opening 17. The casing 18 has the iront endclosed by a plate 20 bolted into position, and at its sides the casingis provided with flanged openings 21. Said casing 18 is fastened to theflue sheet by stud boltsl22, also by rivets located between the studbolts as indicated by the broken lines in Fig. 2. Extending through theopenings 17 and 19 is a sleeve 24 preferably of brass, and within theinner end of this sleeve is snugly fitted the front end of the dry steampipe 16. Said tube 24 has a conical enlargement 25 at its front endWithin the casing 18, and said enlargement bears against the wallssurrounding the opening 19 Which walls are beveled off to form a tightor ground 'joint between the enlarged end of the tube and the casing.Said end 25 of the tube 24 is held forcibly engaged with the walls ofthe opening 19 in the casing 18 by means a collar 26, the centralorifice of which registers with the opening of the tube 24 and whichcollar is clamped against the front end of the tube by means of nuts 27working on the stud bolts 22.

28 indicates the steam delivery pipes which are two in number arrangedone at each side of the smoke box and are curved from the casing 18toward opposite sides of the smoke box downward therein to thedischarge. The steam pipes 28 have fianged ends 29 bolted to the flangesof the openings 21 in the casing 18, and if desired gaskets 30 may befitted in the joints, as shown.

In operation the dry steam passing from the boiler through the pipe 16enters the casing 18 and is there distributed through the pipes 28 tothe discharge, while the gases of combustion pass through the flues 11and into the smoke box and thence out the draft pipe which is arrangedin the usual manner. This arrangement provides as will be seen, a secureand perfectly tight connection between the pipe 16 and the pipe 28without in any way interfering with the usual manner of operating theboiler, The flues may be cut out of the boiler in the usual manner, andby removing the cover plate 2O and elements 26 and 24 the flues may bereadily withdrawn from the `boiler without disturbing the pipes 28 andthe casing 18, and nearly all of the flues may be replaced directly intheir respective holes in the flue sheet, While those flucs lyingdirectly opposite the pipes 28 may be introduced through the adjacentholes and moved laterally for a distance equal to that between the twoopenings in the 4flue sheet.

After the collar 26 is once set up firmly against the tube 24 apractically hermetic joint is attained and the parts when properlyassembled will remain serviceable for practically the life of the boilersince they are not exposed to extremes of temperature, corrosion andlike destructive conditions.

Having thus described the preferred form of my invention, what I claimas new and desire to secure by Letters Patent is:
